How Twitter teaches Scala

on YouTube ↗24m

" summary

Twitter migrated from Rails to a Scala stack around 2009 and now runs Finagle/Finatra microservices; onboarding is a four‑day engineering intro that walks new hires through building a real service, covering nonblocking code with futures, implicits used in framework APIs, and a pragmatic subset of Scala so application code stays simple while the framework uses advanced features. A documented learning path includes a Scala primer and 12‑hour essentials, collections and futures classes, plus a 1:1000 instructor-to-engineer ratio and TA shadowing to scale teaching.
